TDIRIGIBLE Specification of Letters Patent.

Application ined June 30,5191-1. serian No. 636,164.

Be it known that I, GEORGE J oHN ,Baking Yresiding at .Republid vin .the county .of Fayette and State ot' Pennsylvania, have Ainvented certainniew and useful Improve- ,1 `ments'm Dirigible Headlights, of which. the

following is a specification, Areference being l' had therein to the accompanyingdrawing.

This invention relates to dirigible'heiul flights' yfor vehicles, especially automobiles, `yandfthe objects of my invention are to tur* nish an automobile with a head light,l.nnp, frlanterns that. will be' automatically shift-5 ed `to cast its rays Vof light in the path'of the p fautomobild'and' to provide a vi'nechanism Jror p 'thealoo've purpose that isapplicable to' various types of vehicles.

"Further obJects of my invention'are to provide a vehicle with an automatically f -shifted lamp actuated through the medium i of the steering-post and spindles of theautomobile, and to accomplish the above re- `l stilts by a mechanical construction, including tensionv devices that `compensate `for the differences 'in the movement of a vehiclebody or the spindlesof the forward axle of the vehicle.

lVith the aboveand other objects `in view, the invention resides in the novel'construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

` Reference will now be had to the drawing herein z-Figure 1 is a longitudinal view ot' the lamp shifting mechanism as applied to an automobile; Fig. 2 is a plan of the same, and Fig. 3 is an elevation of a detached lamp.

The reference numeral 1 denotes the side frames of an automobile, 2 the engine hood supported by said frames, 3 an axle having knuckles 4, and wheel spindles 5f-all or' these parts being common in the ordinary and Well-known types of motor driven vehielos.I

Secured to the forward end of the enggginfI hood 2, at the side edges thereotfas at (3. are depending converging arms T, and secured to the underneath side of the 'trames 1, as at 8, are forwardly projecting converging arms 9. The converging ends ot the arms 7 and 9 are formed integral with a yoke 10 and revoluhly mount ed in said yoke is a vertical lamp post 11, The post 11 has secured Ato the p ost.

rectangular portions 12 and 13, the former support-ing the huh 14 of a horizontal sprocket wheel l5; The p ost lllhas a collar 16, adapted to support the rearwardly proto extend through the openings of the brackets 17 and engage-the uppermost fbracket, as best shoivnin F ig. 1. lThe upper end of the catch 'is beveled, whereby the brackets catch; The post is retained in engagement with the yoke 10 by the washer Q() and the cotter pin 21, arranged in an opening 22 provided therefor in the lower endof the post. l l y Suitably secured to the spindles 5 are thev lrearwardly projecting portions 23 of inwardly projecting arms 2t. said arms having `'the innerendsthereof bentupivart'lly and. apertnred to provide eyes 25. Connected to the eyes 25 `are the eyelet ends of rods 26, saidrods extending into casings 27 attached to chains 2S ot the ordinary type, said chains being connected to the eudsof a sprocket chain 29 that passes over-the sprocket Wheel' 15. The rods QG within the casings 2T are provided with heads 30` and encircling said rods, between the rear ends oi the casings and theY heads 30 are coiled compression springs 3l. The coiled compression spring 32 can be arranged between the collar 16 and the yoke 10 to cushion a` movement of Vthe lamp 18 relatively to the yoke 10, thereby preventing th.` lamp from being unduly jarred or subjected to vibrations that might injure. the lamp.

As the body of the automobile is movably supported with respect to the axle 3, the body carrying the lamp can move, since the. tension devices, including thc elements 2G, '27, 3() and 31 take up slack in the chains 2S and Q51 and normally maintain the same taut.

lt. is apparent that when the spindles l 5 are moved by the steering` post of the i automobile that the chain 2l) will be shifted l to rotate the post l1 in a direction that will carry the lamp 1S in a plane parallel to the forward wheels of thc automobile; conse fluently. the rays of light will be always cast in the direction in which the automobile is l traveling.

The catch isadapted can easily ride lover the upper end of 'said i The invention, with a few changes, can be used 11i-connection with a locomotive, and

l while in the drawing, there is illustrated a. preferredl embodiment of the invention, it is to be understood that the structural elements are susceptible to such changes as fall within the scopeof the appended claims.

What Iclaim 1s:-

1. In a dirigible headlight for automobile's, the combination with side frames, an engine hood, and the wheel spindles of t-he automobile, of converging armssupported by said frames and said hood, a yoke carried by the forward ends of said arms, a post revolubly mounted in said yoke, lamp brackets det-achably mounted upon Asaid post and adapted to support a lamp, a sprocket wheel mounted upon said post within said yoke,

A inwardly projecting arms carried by said wheel spindles, and a liexible connection between said arms and including a sprocket chain passing'around said sprocket wheel.

2. In a dirigible headlight for automobiles, the combination with side frames, an engine hood, and the wheel spindles of the automobile, of converging arms supported by said frames and said hood, a yoke carried by the forward ends of said arms, a post revolubly mounted in said yoke, `lamp brackets detach-ably mounted upon said post and adapted to support a lamp, a sprocket wheel mounted upon said post within said yoke, in- Wardly projecting arms carried by said wheel spindles, chains connected to said arms, a sprocket chain connect-ing said chains together and passing around said sprocket wheel, and tension devices, including casings and springs attached to maintain said chains taut, and compensate for the movement between said arms and said yoke.

3. A dirigible headlight for automobiles comprising converging and forwardly-projecting arms supported from the machine, a yoke carried by the forward ends of said arms, a post revolubly mounted in said yoke, lamp supporting means carried by the post, a s rocket wheel connected to the post and positioned within the yoke, oppositely-dis posed and inwardly-projecting arms carried by the forward wheel, spindles of the machine and shifted thereby, and a shiftable fiexible element connecting said arms together and includingor a sprocket .chain engaging with said sprocket wheel for rotating the postwhen either of the inwardly projecting arms is shifted.

4. A dirigible headlight for automobiles comprising converging and forwardly-projecting arms supported from the machine. a yoke carried by the forward ends of said arms, a post revolubly mounted in said yoke, lamp supporting' means carried by the post, a sprocket wheel connected to the post and positioned within the yoke, oppositelydisposed, and inwardly-projecting arms carried by the forward wheel spindles of the machine and shifted thereby, and a shiftable flexible element connecting said arms together and including' a sprocket chain engagingwith said sprocket wheel for rotating the'post when either of the inwardly projecting arms is shifted, said element further including a tensioning means for maintaining the same-taut when said cham is shifted in either direction.

In testimony whereof I affix my signature in the presence of two witnesses.
